Conservationists followed up the reports two months later, and managed to track down the animals in August. They have only been seen twice before in Kenya and Tanzania.

"They were so close and extremely calm and seemed not disturbed by our presence," the HCP said.

"The mother kept pacing back and forth a few yards infront [sic] of us while signalling the baby Giraffe to hide behind the bushes — a characteristic of most wildlife mothers in the wild to prevent the predation of their young."

Take a look at the HCP's video below, which has been online since August, but started gaining attention online in mid-September:

The giraffes are this colour because of a condition called leucism.

It's different from being albino, which prevents animals and humans from producing any kind of pigment, as can be seen in their white skin and pink eyes, according to the National Geographic.

Leucism, however, leaves animals mostly white but still able to produce pigment on some parts of their body, like their eyes. The white giraffes in the video have dark eyes.

The baby giraffe's skin is also darker than its mother — as can be seen in the light brown spots all over its body — but the HCP believes they will fade as the baby approaches adulthood.

The map below shows the locations of the three white giraffe sightings:

Giraffes, the world's tallest land mammal, are listed as "vulnerable" — one step below the "endangered" category — by the International Union for Conservation of Nature (IUCN), which estimate about the current population to be just over 97,500. They are predominantly found in southern and eastern Africa.

It's unclear whether the white giraffes are still at the Ishaqbini conservacy or whether its staff are taking care of them. Business Insider has contacted the HCP for comment.
